Undifferentiated connective tissue disease and its cutaneous manifestations

Undifferentiated connective tissue disease (UCTD, also named UCT syndrome, latent lupus or incomplete lupus) is regarded as an autoimmune disorder in which signs and symptoms are widely variable and evocative for connectivitis but not sufficiently evolved to fulfil any of the accepted classification criteria for the defined connective tissue diseases. In this paper we describe the case of a 47-year-old woman affected by UCTD according to the preliminary classification criteria supplied by Mosca et al. in 1999.
